The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.

Zinc complex greases with different complexing acids having dropping points comparable to lithium greases and tailor-made dropping points can be made by processing at low temperature in open as well as close kettle process. The present invention discloses a process of manufacturing Zinc complex greasesthrough reaction of fatty acid and complexing acid with zinc oxide in mineral oil to obtain zinc complex greases having high dropping points of 180 to 280 C.

Provided is a lubricating oil composition for a transmission having excellent gear properties, clutch properties, cooling properties, and electric insulating properties. The lubricating oil composition for a transmission preparing by blending (A) a base oil, (B) a viscosity index improver having a mass average molecular weight of 10,000 to 50,000, and (C-1) a polyamide and/or (C-2) a polyol ester, the base oil (A) including (A-1) a synthetic oil having a kinematic viscosity at 100 C. of 1.0 to 10.0 mm.sup.2/s.

A dispensable grease sealant includes a base component in an amount of 50 wt % or more, based on a total weight of the sealant, and a thickener. The base component is selected from a group including a silicone wax, a liquid rubber, and a combination thereof.

The invention is directed to a method for reducing low speed pre-ignition events in a spark-ignited direct injection internal combustion engine by supplying to the sump a lubricant composition which contains an oil of lubricating viscosity and an ashless dispersant. The ashless dispersant may be selected from succinimide compounds prepared from aliphatic or aromatic amines.

The present invention relates to a refrigerator oil for a mixed refrigerant containing less than 40% by mass of an unsaturated fluorinated hydrocarbon compound (HFO) on a basis of the whole amount of the mixed refrigerant, the refrigerator oil containing a base oil (P) including at least one selected from the group consisting of a polyvinyl ether (PVE), a polyalkylene glycol (PAG), a copolymer (ECP) of a poly(oxy)alkylene glycol or a monoether thereof and a polyvinyl ether, and a polyol ester (POE), with a hydroxy value of the base oil (P) being 15 mgKOH/g or less; and a refrigerator oil composition containing the foregoing refrigerator oil and a specified refrigerant.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.

The invention is directed to a method for reducing low speed pre-ignition events in a spark-ignited direct injection internal combustion engine by supplying to the sump a lubricant composition which contains an oil of lubricating viscosity and a boron-containing ashless dispersant. The ashless dispersant may be selected from succinimide compounds prepared from aliphatic or aromatic amines.
